#3901 [FVT]after change mic node bridge between internal bridge and external bridge, ip cannot ping from host node to mic node
After change mic node bridge from external bridge to internal bridge or internal bridge to external bridge, bridge can be configured in mic node,but ip cannot ping from host node to mic node; That is to say,bridge does not take effect.
The work around:reboot host node,it can take effect;
reproduce steps:
1, change external bridge to internal bridge for mic node
chdef c902f04x31-mic0 micbridge=192.168.1.31 micbridge=micbr0
2,update /etc/hosts for mic node,makedns,makedhcp in MN
3, nodeset for mic node
nodeset c902f04x31-mic0 osimage
4,check ifconfig for mic node:
mic0 Link encap:Ethernet HWaddr 6E:92:52:00:8A:E0
inet addr:192.168.1.31 Bcast:192.168.1.255 Mask:255.255.255.0

RX bytes:446397 (435.9 KiB) TX bytes:1350 (1.3 KiB)
5,login host node, ping mic node:
~]# ping c902f04x31-mic0
PING c902f04x31-mic0 (192.168.1.31) 56(84) bytes of data.

check host node :

6,work aroud:
rpower host node off and on, then login host node, it can ping mic node;
Discussion
I do not see what xCAT could do. I'll contact Intel for this issue.
xCAT will not focus on mic support for a while, and this defect is not serious. Move it to 2.9.
Cannot be pending with no fix
Since we lost the dev env and will not put effort on Xeon Phi support in a short time. This bug has been added to feature request: https://sourceforge.net/p/xcat/feature-requests/178/ so that it will be fixed when we work on this feature request.
